EAEVESTING-MACHINE.

To alb' whom it may .concern .f

Be it known that I, CHARLES B. HAZARD,

a citizen of the United States, residing near- Xenia, in the county of Greene and State of Ohio, have invented certain new and useful Improvements in HarvestingMachines, of which the following is a specilication.

My invention relates to corn harvesters, and particularly to shocking devices adapted to receive the several stalks of corn and adapted to discharge the corn` when a predetermined quantity has been collected.

The object of the invention is to simplify the structure as well as the means and mode of operation of such devices whereby they will not only be cheapened in construction but will be more eiiicient in use, easily operated and unlikely to getout of repair.

A further object of the invention is to 20 provide an improved packing device for the severed stalks, improved means of distributing the severed stalks in the receiving comu `partment, and for discharging the severed stalks when the compartment. has been filled.

A further object is to provide improved means for actuating the various operating and interengaging parts.

With the above primary and other incidental objectsv in view as will more fully appear in the specification,` the invention consists ofthe features of const 4 ction the parts and combinations thereof,..the mode of operation or their equivalents, as hereinafter described and set forth in the claims.

In the drawings, Figure 1 is a front elevation of the assembled machine. Fig. 2 is a top plan view. Figj is a side elevation. Fig. 4 is a detail perspective view of the various operating parts removed from the supporting frame, illustrating the interengagement of the parts.

Like parts are indicated by si? i acters of reference throughout the .C views..

The machine comprises a main fr preferably formed of angle irons ein ported on three carrying wh carrying wheel 2 centrally ioca swivel outrider wheels 8' located the forward portion of the ma The machine is adapted to i; rows of standing corn at the sari main carrying wheel being between said rows and the w at the outer sides of said rows. 2 and 3 are carrying wheels o' The machine is adapted to horses or similarly propelled w erating parts are actuated by a other motor 4 carried on the machine a" driving said parts independent of ing wheels.

At the forward portion of the te there are provided vforwardly and de wardly extending dividers adapted to i gage the stalks of corn and guide th the cutting device. The outermost i. comprise rollers 5 journaled: in the frame. These rollers are not power i but are adapted to yield when eng the stalks of corn. The innermost f 6 comprise a frame composed of two par boards between which are mounted e wheels over which travel spr carrying spikes or lingers 8 ad gage and lift the fallen stalks o s rockets and their sprocket chains tiierewith the spikes 8 are e. driven by means of bevel gears 6) one of which is secured upon a shaft 10. The drive shaft 10 is means of a belt or sprocket chain ii. ing suitable sprockets from a cour y 12 journaled in bearings on the main the countershaft 12 being driven by of sprockets and chain 13 or by a heit t' the motor 4. Located on the counter l 12 is a clutch 14. normally engaged w Jdrive sprocket, driving the shiatv adapted to be disengaged the means hereinafter described vv shaft 10 and the parts actuated tn remain at rest- 'thecutting blades move in unison.

the dividers 5 and 6 are the cutting devices comprising stationary blades 15 and reciprocating V-shaped cutting blades 16. The reciprocatin opposite sides o the machine are secured tti) a reciprocating bar 17 mounted in suita le bearings 4on the main frame whereby These cutting blades are best shown in Fig. 2. To reciprocate the cutter bar 17 there is pivoted to the main frame a lever 18 (see Fig. 1) bifurcated at its upper extremity or provided with rollers 19, which rollers form a bifurcation. Carried on the countershaft 12 is a cam member 2O engaging the bifurcated u per extremity of the pivoted lever 18.

e cam member 20 .upon its rotation with the shaft 12 is adapted to oscillate the lever 18 upon its pivotal connection. At its lower extremity the lever 18 is connected by a link 21 with the cutter bar-17 whereby each oscillation of the lever 18 will cause a reciprocatory movement of the cutter bar and thereby a corresponding movement of the movable cutter blades 16; the stalks of com having been elevated and held by the spikes 8 during the cutting o eration and havin been severed by the b ades 16 pass into t e restricted passage 22 which leads from the cut-ting device to the receiving compartment. While in the passa e 22 the stalks of corn are enga ed by the elical packers 23 which project t rough the inner wall of the passage 22 and substantially across said passage. The packers 23 are in the form of a double conical helix pivotally supported in the main frame; that is, the packers are helical in form and are of greater diameter at their central point than toward either end, thuc increasing gradually from the forward end toward the center then decreasing from the` center toward their rear end. This will be seen more clearly in Fig. 8. The packers 23 are angular or non-parallel in their relation to the passages 22. This permits the driving connection including the pinions 24 and sprocket wheels 26 and. corresponding sprocket chain as hereinafter referred to, to be located beyond the "wall of the passage and at a point some distance removed therefrom whereby the severed stalks or the blades thereof can not become entangled in the driving mechanism. In order that the peripheries of the packers may extend parallel throughout a portion of their length with the outermostwall of the passage, the rear portion of each packer is tapered or conical. The angular arrangement of the packer and the passage providesI a converging entrance to the passage between the periphery of the forward portion of the packer and the side of the passage, even in the event that the forward portion of the packer is formed straight or cylindrical; however to increase ille angle of convergence of the cutting blades 16 at the" mouth or entrance of the passage, the helical packers are preferably tapered or formed conical at their forward portion as shown in the drawings, thus providing for more easy ingress of the severed stalks. The packers 23 are four in number two located on each side of t-he machine. packers is adjacent ,to the upper portion of the frame and the other of the pair is in the lower portion of the frame. The ackers 23 are revolubly driven from the sha` t 10 by means of a pair of bevel gears 24, one of the gears 24 being loosely mounted on the shaft 10 and engaged therewith by a clutch 25 whereby sald packers 23 may be disengaged and the shaft 10 rotated independent of the packers. The upper packer member of each pair is thus driven directly from the drive shaft 10. lThe lowermost packer on each side of the machine is driven from and in unison with the upper packer by means of a sprocket chain assing over sprocket wheels 26 on the shafts of the respective helical packers. The severed corn is moved through the passage way 22 and into the receiving compartment in the rear thereof by the screw like action of the helical packers. The rear ortion of the machine is divided centrally y a vertically disposed housing 27 inclosing the central carrying wheel 2. On either side of the housing 27 is a receiving compartment, the outer sides of which are formed by pivotally mounted frames 28 journaled in suitable bearings 29 on the main frame. The pivotal frames 28 are connected at their rear extremities by link rods 30 which forms the rear closure of the compartment and holds the frames 28 in normal position. Carried on the frames 28 are a plurality of resilient spring arms 31. Pivot'ally connected with the extremity of the spring arms 31 are rods or links 32 which extend through loops or bearing rings 33 on the frame 28 and are adapted to reciprocate in said bearings. As the severed corn is forced back into the receiving compartment it first fills the space 34 and thence successively into the small spaces 35, 36, and 37 there being less resistance to the movement of the severed stalks from each space to the next succeeding one than would be required to cause the flexible spring arms 31 to be forced outward. lVhen the severed stalks have reached the rear end of the compartment in a posi tion adjacent to the center housing the continued forcing back of the severed stalks gradually forcesthe outermost spring arm 31 or that extending farthest rearward outward to compensate for the increased quantity of severed'stalk's. The remaining spring arms 3l are gradually forced outward and in turn as shown more particularly lin Fig. 7 in' which the two outermost spring arms have been flexed to their limit, the third spring arm almost to the limit, and the rene of each pair of.

maini two arms still in normal position. It will e seen that the spring arms 31 thus keep the severed stalks compact while in the receiving compartment and serve to hold them in upright position. The severed stalks contained in the receiving compartment, whether a large or small quantity, are always under pressure of the spring arms. When the compartment has been lilled thc spring arms and their links will assume the position shown in dotted lines in Fig. 7. It then becomes necessary to discharge, the load of severed stalks.

The bottom sections 38 of the receiving compartment are each supported on an oscillating shaft 39 supported at its forward end in bearings in the main frame and provided at its rearward end with bearings in arms 40 projecting laterally from the central houslng 27. In discharging the load from the receiving compartment the link bars 3() at the rear of the machine are disconnected and the side frames 28 are swung `outward about their pivotal connections 29 to release the load of stalks andsthe bottom sections 38 are oscillated or inclined lsimultaneously with the movement of the frames 28 to discharge the load outward. To cause this movement ot said parts there is provided on the frame of the machine adjacent to the forward end of the central housing 27 pivoted bell levers 41. Said levers are pivotally connected at their upper extremity with a reciprocating rod 42 extending rearward immediately above the housing 27 and supported at its rear end by pivoted arms 43. The rear end of the rod 42 is turned downward at at 44 to form a handle or grip and at its forward end it carries a pivoted latch member 45 engaging one of the transverse bars of the main frame l to hold the bell levers 41 and the pivoted arms 43 in their normal position. .Extending rearward from the latcl'i 4:3 to a point adjacent to the handle 44 and supported in suitable lir'ifpers on the rod is a latch rod or link 46 by which the latch 45 may be disengaged from the frame by the oi'ierator at the rear of the machine. ll'hen so disonA gaged, the reciprocating rod 42 is pulled rearward which oscillates` the bcll levers 4l on their pivotal shaft 47. Each or"d the bottom sections 38 of the receiving compartment is provided with a projecting arm 48 best shown `in Fig. 4. The lateral arm 49 of the bell lever 41 is connected by a link 50 `with the projecting' arm 48 oi the corre sponding bottom section 88 ot thc receiving compartment and upon the oscillation of the bell lever 4l. hv the rearward movement of the rod 4. th- Bottom section 38 oscllated to an inclined position as shown in dotted lilies in li`ig. 4 discharging the load of severed stalks carried thereby outward. The oscillation of the bottom section 38 which is secured to the supporting shaft, 39 causes a corresponding oscillation of said shaft. The supporting shaft 39 carries a rock arm 51 connected by a link 52 with a rock arm 53 upon the pivotal shalt 54 of 70 thc side frames 28. The movement of the supporting shaft 39, due to the oscillation of the bottom section 38, operates through the rock arms 51 and 5l and link 52 to cause a simultaneous outward oscillation of the side frame 28 to the position shown in Fig. 8. In Fig. 8 the bottom section is shown in its inclined or operated position and the side frame in its outermost position as at the time of the discharge of the load from the compartment. There is also carried on the supporting shaft 39 a rock arnl connected by a link 56 with a pivoted shift lever 57 supported on the main frame and adapted to move the clutch 25 t0 and from operative position. The construction is such that at the time the load is discharged 'from the receiving compartment by the oscillation of the bottoml and outward movement of the side frame the helical packers 23 will be automatically disconnected from the driving mechanism and will remain at rest until the parts have again been returned to normal posit-ion. After the load has been discharged, it is necessary to advance the machine a short distance to clear it from the discharged stalks before the parts may be returned to normal position. Any corn which is cut during this limited forward movement, while the parts are in discharging position, will be collected in the passage 22, but inasmuch as the packers 23 are in-operative through the disengagement of the clutch 25, such stalks will notbe advanced through the passage 22 and the receivig compartment until the parts are again in normal position. To return the parts to normal position,the operator pushes Ithe reciprocating rod 42 forward until the latch 45 again engages the transverse bar of the frame. This forward movement of the rod 42 oscillates the bell levers 41 which, through the connecting link 50 returns the bottoni sections 38 to normal position, at the same time oscilla-ting the longitudinal shaft 39 on which the bottom section 38 is rigidly secured. The oscillation of the shaft 39 operates through the rock arms 51 and 53 and link 52 to simultaneously return the side frames 28 to normal position and also cause the renga ement of the clutch 25 by means of the shi? the link 56 and rock arm 55. The link bars 30 at the rear of the machine are then reengaged and the machine is ready'to proceed as before.

The machine is adjustable for severing corn at ditlerent heights `from the ground by adjustment of. the outrider wheels 3, the frame of the machine tilting on the -main t lever 57 operated by carrying wheel 2. The outrider wheels 3 are provided with swivel connections 60 pivoted to the forward end of an arm 61 projectingforwardly from a transverse shaft 62 Journaled in the main frame. At its inner end the transverse shaft 62 is provided with a rearward extendin arm 63. It is to be understood that there 1s a transverse shaft- 62 and a rearward extending' arm 63 on each side of the machine. Carried on a transverse revoluble shaft 47 located in the upper forward portion of the central housing 27 and preferably the same shaft upon which are pivoted the bell levers 4l, are winding drums 65. Cables 66 are earried on said winding drums 65 and are attached to the rearward extending arms C3. Also carried on the shaft 47 is a worm wheel 67 engaged by a worm 68, on the extremity of a shaft 69 extending rearward within the housing 27. At its rear extremity the shaft 69 is provided with a crank 70. Byithe rotation of the shaft 69, the winding drums 65 are rotated, Winding the cables 66 thereon, and'thereby oscillating the transverse shaft 62 in their bearings in the main frame, the wheel supporting arm 61 being rigidly connected with the transverse shaft 62 will cause'the forward portion of the machine to be elevated upon said operation ot the parts.

livotally connected with the swivel head 60 of the outrider wheel 3 and also with the main frame is a compensating link 7l extending parallel with the supporting arms 61 and serving to maintain the swivel head 60 always in vertical position.

Extending through the housing 27 is a reciprocating rod 72l having a handle 7J formed at its rear extremity and at its forward end being connected with the pivoted shifting lever '74 carried on the main frame and engaging the main driving clutch 1l (see Figs. 1 and 2). By reciprocating the rod 72 the operator may. atI any time, from the rear 0fthe machine` disconnect the driving motor 4 from the operating mechanism.

ln the drawings, the spring arms 3l have bceii shown as extending substantially acrossl the receivingl compartment but not entirely so. Vllo\\'ever. in practice it is pret'- erable to extend these .spring arm.` 3l to the contral housing 27. the upper series ot spring arms being preferably extended even beyond the housing and substantially to a point in alinement with the reciprocating rod 42. 'l his is especi-.illy desirable if the corn is not luxuriant. but thc stalks thin and light.
